New cast members aren’t the only additions to The Real Housewives of Orange County this year. A brand new baby is coming to the OC to make Housewife Vicki Gunvalson a second-time grandma! The series veteran broke the news yesterday that her daughter Briana Wolfsmith-Culberson is expecting again, and it’s a boy!

Vicki took to Twitter on Thursday to make the exciting announcement. “So excited! Just found out baby #2 is a BOY! #troybigbrother #bestfriends #footballplayers.” Included was a picture of Briana, 26, her husband Ryan and their15-month old son Troy, smiling and posing with a bunch of blue “It’s a boy!” balloons.

Briana, who’s a nurse, has appeared on numerous episodes of The Real Housewives of Orange County, spending time with her mom and having those all-important mother-daughter talks. She was also included in last season’s reunion show, where the normally mellow young mom got into the Housewife drama after confronting Vicki’s off-and-on boyfriend Brooks Ayers.

In spite of her feelings about Brooks, however, it’s obvious that Briana values her relationship with her mother. The two have an extremely close bond, a fact that Briana touched on in a Bravo blog post last year.“Having Troy has allowed me to feel more empathetic for my mom and how amazing she is as a mother,” Briana wrote. “Throughout my life she has always put my brother and myself first and was always focused on our happiness. If I’m half as good of a mom as she is, then I’ll have done something right.I want to be the best mom that I can be for him, and with every decision I make, I have him in mind. I want him to be proud of me and know how much I love him.”
